Abstract
The hot-dip aluminum alloy plated steel has a base steel and a plated layer, in which the composition of the plated layer contains, by % by mass, Fe: 25% to 75%, Mg: 2% to 20%, and Ca: 0.02% to 2% with a remainder of Al and inevitable impurities, the plated layer contains one or both of an α-Mg phase and an AlMgphase, and the sum of the partial volume fraction of the α-Mg phase and the partial volume fraction of the AlMgphase in a range of a depth of 5 μm from a surface of the plated layer is 1% to 40%.
